When I dial a phone number, I
can not hear any sound and the
LCD always shows “Please
Dial…”
Power off and power on the IP phone, and try again.
The voice quality is very poor
during my conversation
There are very heavy internet activities in your network, such
as uploading or downloading a huge amount of data from the
Internet. Try to limit such activities to improve the quality.
I can make outbound calls, but I
can not receive incoming calls
Refer to Configuration via Web Browser section and check
the phone settings area, make sure the ring type and ring
volume are set properly.
If you are using a router or firewall, check with your VoIP
provider to make sure it supports NAT traversal, and find out
which port(s) is needed to allow incoming calls. Then follow
the instruction in Appendix to enable the Port Forwarding.
LCD shows incorrect date and
time
Refer to Configuration via Web Browser section and in “other
setting” area:
Check the sntp ip, or try another time server address.
Check the timezone setting.
Check the daylight saving option.
